Event Description
|
It was reported that a patient underwent a paroxysmal atrial fibrillation (afib) ablation procedure with a carto® 3 system and a map shift issue occurred.There was a map shift with no errors on the carto 3 system.The caller stated that the patient didn't move.The caller also stated they had started ablation on the left-sided vein when they felt like the fast anatomical mapping (fam) was incorrect.They moved the catheter to the right-sided veins and the intracardiac echocardiography (ice) image was not matching the fam image.The caller stated the fam displayed the catheter on the posterior wall.The caller stated that the respiratory graph went flat and the tidal volume was reduced.They re-mapped and the issue was resolved.Map shift did not duplicate, upon speaking with the biosense webster inc.(bwi) representative reported it appears the location pad holder was bent and needed to be replaced.Additional information received confirmed the issue was seen during ablating and no error message was given.Error was noticed using ice in la at the right superior pulmonary vein (rspv) and ablation tip.In ice ablation was at rspv but in fam map it was in the center of posterior wall.The approximate difference in catheter location before and after map shift: approximately 4cm.The physician did not perform cardioversion prior to the map shift and the patient did not move before detecting the shift.
